My phone keeps switching between 3G, 4G, 4 bars, 1 bar, and sometimes no reception at all. I bought the phone from Rogers, and my Fido sim works in it without unlocking.
I'm trying to connect to LTE, which I still have not done, I can't even keep a stable 3G connection.
These are my APN settings:

Any help is greatly appreciated.

Try not setting any APN settings.. I also bought the Rogers one and using it on Fido... did not plug in any APN settings, worked like a charm.

I do see it bob from 3G to 4G when I unlock the phone... but I think that's normal. As for LTE, make sure you have a LTE sim card... I get great LTE in Montreal and getting abou 33m + download speeds

I wanted to join in the conversation to report that I am having the same problem, but have discovered it through my SMS messages not being sent out 1 out of 10 times. Every single time a message could not be sent my phone was completely disconnected from the network, only to get full bars again in a couple of seconds.

Since I've noticed that I have been taking a look at my bars, and they're constantly fluctuating.

Can someone please advise what to do? I constantly get no signal, and my data bounces between 3G to 4G, no LTE, my area has lighting fast LTE, when i insert the same in on my Iphone5...i almost get 33-35mbps. Not sure, why the signal constantly bounces 2-3 bars, then justs dies at 0....is this an hardware issue? did you guys manage to solve this?

humm not sure. i'm going to try with my rogers sim, if i still get the same issue..then i'm just out of luck...i really think it could be a carrier profile issue? is there an update? and if the still persists, can i send it back to nokia for a replacement considering the fact that i bought the phone from kijiji, but here in montreal, i get really amazing LTE reception on my iphone5. I really hope i can use the lumia, looked really promising.
